Colors and Enneagram Types

I am making a shoot into the breeze with this as a first attempt, I'll probably edit it later but I am writing this off of first intuition. Feel free to post your take on it, it will likely differ from mine.

I think Nines would have to be purple, since it's the most passive colour, imo. Which is weird, since I identify with greens more, and i think they're just a little more vibrant and "Hey, I'm over here!" than purple...

Which again is weird, because when you see some purples in nature, they really stick out over the greens around them.

EDIT

Depends which kind of purple. Warmer purples are obviously more aggressive, as warm colours are wont to be.

Purple sticks out because not much on earth is naturally purple.

Purple is seen alot in the cosmos/sky though, so to me purple has always been related to the cosmos. This probably relates the detachement of 9's and the wide-spanning univeralisty of their intuitions.

I also find darker rich shades of purple to be calming, which relate to the peacefulness of 9's.

Sunsets naturally show purple
Aurora's in the sky show purple
Certain distant astronomical phenomenona in space show purple
